MIX8421 Electrochemical 0-20ppm Sulphur Dioxide (SO2)Gas Sensor High Selectivity For SO2 Gas Monitors
MIX8421 Electrochemical 0-20ppm Sulphur Dioxide (SO2)Gas Sensor
Principle Introduction:
MIX8421 is an electrochemical SO2 sensor developed by Mixsen. It uses the principle of electrochemistry. There is a reference electrode inside the sensor, which greatly improves the stability of the sensors. When the sensor senses the sulphur dioxide, the working electrode and the counter electrode react with the redox reaction, through measure the current to get the concentration of sulphur dioxide.
Feature:
High selectivity for SO2 gas
High accuracy
Linear output
Environmental protection design
Application:
* Industrial SO2 gas monitors leakage detection
